.To @ZZ whom it may concern:

B e it known that I, CHARLES PERILLAT, a citizen of France, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Hydrocarbon-Burners, of which the following description, in connection with the act'zompanyi'ng drawings, is aspecilication, like letters and figures on the drawingsrepresenting like parts.

This invention relates to ahydrocarbon-` burner especially designed and adapted for, heating purposes, but which may alsobe Aemployed for lighting.

heat may be obtained with a yniiriilnumconsumption of fuel. For this purpose I employ a perforated or forarninous jacket surrounding a vaporizing tube or chamber and communicating with a mixing chamber, into which the vapor from the vaporizing-tube is discharged and admixed with air and from which the heated mixture of air andvapor descends into the foraminous jacket and is consumed on the outside thereof. The foramt inous jacket and mixing-chamber are prefert ably surrounded bya cylinder or casing forinlng a combustion-chamber, and which also serves as a chimney to concentrate the heat,

as will be described. These and other fea- V tures of this invention will be pointed outin the claims at the end of this specification.

Figure 1 is a vertical section of a hydrocarbon-burner embodying this inventiongFig. 2, a sectional detail on the line 2 2, Fig. l; and Fig. 3, a sectional detail, on an enlarged scale, to be referred to.

Referring to Fig. l, a, represents the Vaporizing tube or chamber, which is secured'liquidtight by brazing b or otherwise securingto a fitting c, having attached to its upper end a shallow vessel or cup cl, which surroundsthe vaporizingtube i andis designed to contain alcoholto startthe burnerin operation. The fittinglc has .its bottomlclcsed by a screwthreaded `plug f,- having a central boreor openingthrough Whichis extended a needle g, adapted to clean the vapor-outlet orifice in a cap h, inserted int-o the upper endof `the tube ct, The plug f has secured to it liquidtight by brazing t' a small tube j, extended up intothe vaporizing-tube ct to near the upper end thereof, the tube j forming within the tube ct a liquid-tight chamber k and preventing leakage of oil out of 'said chamber through the bottom of the fitting c, thereby enabling the needle-valve g to be removed when broken `or when desired without danger or leakage of oil through the hollow plug f. The central bore or opening in the plug f may be enlarged to form a chamberlfor the reception of packing, (not shown,) but `which surrbunds the needle and prevents escape of The invention has for its object'to provide a simple and efiicient burner of the"class'de scribed which is practical, easily accessible, Q readily cleansed, and with which an intense actuating-lever at, pivotally secured to abracket or arm o, depending from the fitting c, the said lever coperating with an adjust- 4ing-screw p, carried by a lug r on said fitting. The iitting chas communicating with itan oil'- inlet passage 2 in a valve-fitting 3, provided `with a valve 4, controlling the admission of the oil into the chamber 7c, the valve-fitting 3 having an inlet-passage 5 connected to a suitable source of supply. (Not herein shown.)

The vaporizing tube ot` is extended up through the bottom 6 of a jacket or cylinder 7 of perforated or foraminous material, which hasits upper end extended into a cylinder or casi'n g 8 (see Fig. 3 and dotted lines,Fig. 1) and brazed or otherwise secured thereto. The casing 8 is closed at its upper end 10 and forms a mixing-chamber for vapor and air; The casing 8 has extended up into it to near its closed upper end 10 a vertical tube or pipe l2, having horizontal branches 13 14 extendedr through said casing and perforated jacket, and, as herein shown, into pipes 15 16, projecting through an outside cylinder or casing 1.7, the branches 13 14 constituting air-supply pipes for the burner. The tube 12 and'its branches 13 and 14 are fitted into suitable semicircular notches in the` upper edge of the jacket 7 before the casing 8 is `fitted onto the said jacket.

The cap lt of the vaporizing-tube ct `preferably extends through an opening in the air-supply pipes in line with the vertical pipe 12, so that the vapor discharged through IOO `sof "l vaporouuet Off@ formino jacket vaporizing-tu-beaudwith `.the said ja ke the orificepin said cap may pass directly-up into the' pipe 12a-nd draw through the branch pipes 1314 a supply of air, which is thoroughly commingled with the vapor in the tube or pipe 12 and also in the 'mixingchalnber 8, down through which it descends into the foraxninous jacket, from which it issues through the perforations or meshes thereof and is ignited within the casing .17, from which the flame issues at the center of support 20, which may be aspider or open frame, and which is secured to a base 21 .by stay-bolts 22. The quantity ofk air vadmixed with the vapor may be regulated' by suitable disks or valves 23, having threaded stems 24, extended through thread-edopenin gs in crossbars 25, secured to the pipes 15 16. The upward current of air and vapor is arrested by the .closed end 10 of the casingB, thus assistingin thoroughly mixing the air and vapor.

The needle g may be raised and lowered by means of the lever fn, and the amount of va- V por .issuing from the vaporizer may be regul.lated by limiting theupward movement of` z 5 said lever, which is effected by the adjusting- .screw p. i

The alcohol-cup surrounds-thelower part of the vaporizing-chamberand is readily accessible,.as is .also the needle, the screw m, and the hollowplugf, so that these parts may be readily removed. The fitting cis supportl edffromthe base 21, as shown,by a bracket 2,6. i The .heated mixture of vapor and air passes down from the mixng-chamberrabout thef Aupper portion of the vaporizing-tube, therei by keeping the said tube sufficiently'ho-t tovaporize the. oil Aadmitted therein through Q theinlet-passage `2, the flow of oil into the air. passing up through said casin'gup above ing-.chamber 8; but while `Iinay prefer to 'forfthe mixing-*chamber and theforaminous FLO/keb A. .7..- .t .Y l In hydrocarbon-burners of the class d cap 4for the vaporizing tube substantially smalland in order to prevent-the needle being forcedup through this orifice, and: thereby ,me'ntfof thelever n. l -Icl`ai1n l.
